In Figure 7 which relates, to the same mechanism, the modification hasthe'foll'owing form 7 Between the enlargements 24 and 25 the hinge isdivided into two parts. The spatu- 1a 10 of C sharp G sharp is subjectto the action of the hinge 1 and the pointed support of G sharpand theheel 55 is subject to the action of the hinge 2'. As in Figure 7 4,there is a rockable member 53 and a pivot 52, these parts remainingunchanged. The difiierence, however, is that the heels 10 and 55 areapplied to the rockable member in the reverse direction,from thedirection ofFigure 2, that is to say, from behind. The pointed supportof C sharp G sharp is under the actionof a weak spring which causes itto lift. The spatulaof C sharp Gsharp is under the action of a springwhich is suf ficient only to lift it and which by its heel bears onthe'rockable member which at its end acts on the heel 55, the laterbeing rigid with the pointed support of C sharp G sharp and which annulsthe action of its spring and causes it to'close. Consequently, when thespatula 10 is lowered the spring of the pointed support of G sharp isfreed and the latter is raised.

What is claimed is I 1. In a keyed musical wind instrument, a tamp-ion,a controlling lever for the tampion, an operatinglever pivoted on anaxis, and a rockable member pivoted on the instrument and adapted to beactuated by the operating lever to actuate the controlling lever.

2. In a keyed musical wind instrument, an axis comprising a plurality ofhinges, an operating lever pivoted on one hinge, a tampion, acontrolling lever for the tampion pivoted on another hinge, a roekablemember pivoted on the instrument and adapted for actuation by movementof the operating lever to in'turn actuate the controlling lever.
